Stocks: Slogging on a 'bumpy, muddy track'

U.S. stocks ended mixed Tuesday, as investors welcomed a better-than-expected report on the U.S. housing market ahead of a key speech by the chairman of the Federal Reserve later this week.

The S&P/Case-Shiller national home price index, which covers more than 80% of the housing market in the United States, rang up a 6.9% gain in the second quarter. Analysts had expected a 0.3% decrease.

"With these numbers, it looks like we continue to be on a road to recovery, but it's not a super highway," said Rex Macey, chief investment officer at Wilmington Trust Investment Advisers. "It feels like a country road, where you're slogging along a slow, bumpy, muddy track."

Macey said that the fact that the positive news on the U.S. housing picture didn't send markets through the roof is a sign of what he calls a "healthy market."

"When you have little changes day-to-day, that's a greater indication of health than when you have the Dow moving triple-digits on a daily basis," he said. "It suggests that people are reacting more rationally and less emotionally, figuring out what the fundamentals really are as opposed to just pulling the trigger based on macro events."

Investors are also gearing up for Friday, when Fed Chairman Ben Bernanke speaks in Jackson Hole, Wyo. Investors are hopeful that he will give stronger hints about taking stimulus action to ease concerns about a slowdown in U.S. economic growth.
